Patent DE-4004454-A1 (DE)
Inventor: MINET RONALD G
IPC: C01B7/04
Filed: 1990-02-14
Abstract: The method comprises two stages:   (1) passing a gaseous current of hydrogen chloride across a fluidized bed of copper oxides and sodium chloride deposited onto a suitable support, the reaction of the hydrogen chloride with the oxides to form a complex chloride taking place in a reactor (11); and (2) passing the chlorinated transport catalyst over a fluidized bed of transport catalyst which contains copper chloride and sodium, injecting a mixture of oxygen and nitrogen, carrying out the oxidizing reaction in a reactor (21) and liberating chlorine from the catalytic mass while the copper chloride is converted into copper oxide, extracting a continuous flow of transport catalyst which returns to the first stage. An absorption/ separation system (47) using carbon tetrachloride recovers the chlorine give off in the reactor (21).   <IMAGE>

IPC: B62D5/12
Filed: 1990-12-03
Abstract: The motor vehicle with power assisted steering, has the toothed rack of the steering linkage connected to the piston rod (14) of a double acting piston (4) which operates in a hydrualic cylinder (3).

Patent DE-4100071-A1 (DE)
Inventor: JUNG RUEDIGER
IPC: F15B1/027
Filed: 1991-01-04
Abstract: The invention relates to a storage charging valve which, for the connection of an inlet P supplying a hydraulic system (10) to an outlet T when an adjustable upper charging pressure in the hydraulic system (10) has been reached and for separating this connection when an adjustable lower charging pressure in the hydraulic system (10) has been reached, has a control piston (42) which cuts off the connection between inlet P and outlet T in one of its two switching positions and restores this connection in the other. A separating device makes it possible to cut off a control union B connecting the hydraulic system (10) to the storage charging valve from outlet T. When the adjustable upper charging pressure has been reached, the connection between the control union B and the outlet T which is a potential source of leaks can be closed by means of at least one sealing component of the separating device. This arrangement makes it possible to produce a completely non-leaking shut-off of the hydraulic system (10) inside the valve between the lower and upper charging pressures.

Title: Contactless double piston of reduced size - is formed from part with bowl-shaped pistons with very thin bases and which taper into thin shafts
Inventor: STRACH LOTHAR
IPC: F02B75/24
Filed: 1991-04-05

Patent DE-4215456-A1 (DE)
Inventor: MATSUZAKI TORU
IPC: H05K9/00
Filed: 1992-05-11
Abstract: A knitted or braided electromagnetic shielding material is formed by interweaving solder-plated (3) metallic or metal- clad wire rods (2). By heating the knitted or braided material, the wire rods (2) are securely soldered to one another (at 5), thus preventing the knitted or braided material from loosening or disentangling in use. Furthermore, the contact resistance between the wire rods is reduced by the solder connections (5). A strip of the resulting mesh (4) can be punched to form a screw hole. An electromagnetic shielding gasket can be produced by cladding a core with the knitted or braided material (4), and the gasket can be easily secured to a housing for electronic components, by using the solder-plated layers of the wire rods to weld the gasket thereto. <IMAGE>
